<p class="style1">Use Case UC09:&nbsp; Manual  Data Acquisition using Global Positioning System</p>
<p>&nbsp;</p>
<p><strong>Primary Actor</strong>:&nbsp;  Configuration Designer</p>
<p>&nbsp;</p>
<p><strong>Stakeholders and Interests</strong>:</p>
<ol>
  <li>Simulation Operator:&nbsp;  Depends upon usable data collected in the field.</li>
  <li>TraffoPackets:&nbsp;  Packet data depends on usable location and timestamp data.</li>
  <li>TraffoBase:&nbsp;  Requires usable packet data to store in the OpenDMTP server.</li>
  <li>TraffoView:&nbsp;  Requires usable data from the OpenDMTP server to analyze.</li>
</ol>
<p>&nbsp;</p>
<p><strong>Preconditions</strong>:</p>
<p><br />
  Working GPS, compass, and transportation are available.<br />
  A valid route has been defined.</p>
<p>&nbsp;</p>
<p><strong>Success Guarantee (postconditions)</strong>:&nbsp; </p>
<p>TraffoPackets are created and sent utilizing  GPS data.</p>
<p>&nbsp;</p>
<p><strong>Main Success Scenario (or Basic Flow)</strong>:</p>
<ol>
  <li>Configuration  Designer begins data collection at starting point of predefined route.</li>
  <li>Configuration  Designer traverses the route.</li>
  <li>Latitude,  Longitude and Timestamps are recoded whenever a change in compass direction  occurs.</li>
  <li>If  compass direction does not change for 10 miles or 10 minutes, record data.</li>
  <li>Complete  data collection when end of route is encountered.</li>
  <li>Compile  data into configuration file to be delivered to Simulation Operator.</li>
</ol>
<p>&nbsp;</p>
<p><strong>Extensions (or Alternative Flows)</strong>:</p>
<p><br />
  &nbsp; 2a.&nbsp; Path dead ends.</p>
<ol>
  <li>Begin  data collection again from starting point and reevaluate pathing variables.</li>
</ol>
<p>&nbsp; 2b.&nbsp; Route may not be traversable.</p>
<ol>
  <li>Reevaluate  routing parameters.</li>
</ol>
